Hi Laurent I am adapting your current omap3-isp-live application to fit our needs (http://git.ideasonboard.org/omap3-isp-live.git/commit/619164a994c8d878249d6c1b8b16c27074a04209). For this I need to implement an autofocus algorithm to control an attached actuator. Let me summarize what components I use: - beagleboard-xm - mt9p031 on leopardimaging li-5m03 - own developed voice-coil-motor (vcm) driven by current regulator ad5821 - kernel 3.5 out of the linux-omap tree To generate a control signal for my vcm, I need to interpret the values generated by the AF engine of the omap3isp, h3a module. I see, that you have already implemented a working auto-exposure functionality with the AEWB module - so I have done the same with the AF module. But now I have problems to interpret the generated values in omap3_isp_af_process. Do you know how the paxel-buffer is structured? I see that the received buffer has the size of buf_size = af->paxel.h_cnt * af->paxel.v_cnt * OMAP3ISP_AF_PAXEL_SIZE; where OMAP3ISP_AF_PAXEL_SIZE is 48 bytes, but what is in the 48 bytes? Have you made some progress in implementing an autofocus algorithm? Thank you for your help and greetings, Florian -- To unsubscribe from this list: send the line "unsubscribe linux-media" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
